I appreciate you for providing details about your concern, Jami. Let me help you save any information you entered in the Memo box field when creating a bill.

As I've tried doing the task on my end, I was able to save the information I entered in the Memo. In your case, you might be experiencing some browser issues which cause QuickBooks to run slow. To rectify this, let's open your QuickBooks using a different browser or a private window. You can use these keyboard shortcuts:
 

• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P
• Google Chrome: CTRL + Shift + N
• Safari: Command + Shift + N

Once done, try to create and save a bill again with a memo. If it works, return to your regular browser and clear the cache. The system occasionally behaves strangely when the browser frequently accesses pages. It could be due to corrupted cache files in your browser. If it still doesn't work, use other supported web engines to learn what computer and browser are needed for the best experience when using QuickBooks.

Unlike before, the cursor won't automatically start in the vendor box when creating a bill. Instead, you'll have to click in that box with the mouse. I understand if it cost you so much time to do it, so I suggest providing feedback to our product engineers about this idea. They may add this feature in future product enhancements to make our program better and more efficient for you to use. You can follow the steps shared by MirriamM above.
